ESTCube-2 is planned to blast off in 2019 and will operate at approximately 680 kilometres (423 miles) above Earth, which is almost twice as high as the International Space Station. However, the satellite is being designed to boldly go much further.
The satellite will serve as a prototype for ESTCube-3, an Estonian mission to orbit the moon that will blast off in the early 2020s. In addition, the European Space Agency is now officially considering a joint Estonian-Finnish proposal to send a swarm of satellites based on the same Estonian design to rendez-vous with hundreds of asteroids.
